Abstract
Crystallographic, thermal expansion and specific heat data obtained fo r a single crystal of a new organometallic nonlinear optical material, triallylthiourea mercury bromide (ATMB), are reported. It is trigonal (space and point groups are R3c and C3v respectively) with lattice pa rameters a=b=11.580 Angstrom, c=28.939 Angstrom, V=3375 Angstrom(3). T here are six formula units per cell and the density is 2.10 g/cm(3). T he second harmonic generation intensity, obtained on a powder sample, is 2.5 times greater than that of urea.
